Magnetic field lines never do which of the following?

Magnetic field lines never do which of the following?

• A. diverge
• B. intersect
• C. rotate
• D. terminate

Answer: (B)

Magnetic field lines show the direction of the field at each point, and at any location the field has a single, well-defined direction. If two lines were to cross, that point would imply two different directions of the magnetic field at the same spot, which isn’t possible. So field lines cannot intersect. They can bend and spread out around magnets, forming smooth, continuous patterns, but they never cross one another.
